Flanged Ball Valve manufacturers explain product information.

1. What are the features of fluorine-lined flange butterfly valves? (Model: D371F-10F)

Features of the D371F-10F manual fluorine-lined flange butterfly valve:

Manual fluorine-lined flange butterfly valves, used for on/off switching and flow control in pipeline systems, are widely used in many fields, including petroleum, chemical, metallurgy, and hydropower. Conventional butterfly valve technology typically employs a sealing structure, using materials such as rubber and polytetrafluoroethylene. Due to structural limitations, these valves are not suitable for applications requiring high-temperature, high-pressure, corrosion-resistant, or wear-resistant properties. A more advanced butterfly valve is the triple-eccentric metal hard-seal butterfly valve. The valve body and seat are integral components, and the seat sealing surface is welded with a heat-resistant and corrosion-resistant alloy. A multi-layer soft-stack seal is fixed to the valve disc. Compared to traditional butterfly valves, this valve offers advantages such as high-temperature resistance, ease of operation, and frictionless opening and closing. During closing, the valve compensates for the seal as the torque of the transmission mechanism increases, improving sealing performance and extending the valve's service life. This type of valve should generally be installed horizontally in the pipeline.

2. What is the purpose of a fluorine-lined diaphragm valve?

The EG41F46-10 fluorine-lined diaphragm valve is a specially designed shutoff valve. Its opening and closing components consist of a steel disc and a diaphragm made of a soft material (a composite of rubber and fluoroplastic). They separate the inner cavity of the valve body from the inner cavity of the valve cover, thereby shutting off the medium in the pipeline.

3. What are the uses and characteristics of fluorine-lined check valves?

Applications of H41F4-10/16 and H41F46-10/16 fluorine-lined check valves:

A fluorine-lined check valve is an active, corrosion-resistant valve that actively opens and closes the disc based on the movement of the medium itself, preventing reverse flow of the medium. It is also called a check valve or one-way valve.

Features of the H41F4-10/16 and H41F46-10/16 fluorine-lined check valves:

Lift-type fluorine-lined check valves only allow flow in one direction and prevent flow in the opposite direction. These valves typically operate automatically. The valve disc opens under pressure from flow in one direction. When the fluid flows in the opposite direction, the combined pressure of the fluid and the weight of the disc closes the disc, shutting off flow. This type of valve includes lift check valves, swing check valves, and wafer check valves.

4. Application Scope of Fluorine-Lined Angle Globe Valves

The J44F46-16 fluorine-lined angle globe valve is suitable for use with various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, various organic acids, strong acids, and strong oxidants at temperatures between -50°C and 150°C. It is also suitable for use in pipelines carrying various concentrations of strong bases, organic solvents, and other corrosive gases and liquids. It is widely used in pipeline systems for media shutoff in the petroleum and chemical industries.

5. What are the applications of worm gear wafer-type fluorine-lined butterfly valves?

Applications of the D71F46 and D371F46 fluorine-lined worm gear wafer butterfly valves:

Applicable to applications requiring reliable sealing and excellent regulating characteristics. These products are widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, particularly in applications involving highly corrosive media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkalis, and aqua regia.
